Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device which is temporarily hung from the ceiling during the construction of a concrete building such as an RC structure or an SRC structure until the finishing work is completed. The present invention relates to a method and apparatus for suspending such a temporary structure.

2. Description of the Related Art FIG. 7 shows an illuminating device as a temporary structure, and exemplifies an F-cable driving type illuminating device which is most frequently used among the illuminating devices.

In this example, the luminaire a uses an F cable c embedded in the upper floor slab b as a power source, and the F cable c and the luminaire a are connected via an exposed electric wire d. .

In the case of the double ceiling as shown in the drawing, the exposed portion e of the F cable c is extended to the lower surface side of the ceiling surface f and is connected to the exposed electric wire d at the protruding portion g.

The following problems have been pointed out in such an F-cable driving type illumination device. That is, since the lighting device is necessary for finishing the walls and floors even after the ceiling finish, the lighting device is required to be F in the finishing process for the entire ceiling.
The finishing of the cable penetrating portion is left, and when this illuminating device is no longer needed, the double labor of removing the exposed portion e of the luminaire a and the F cable c and repairing and finishing the portion is inevitable. ing.

Generally, in the case of a double-ceiling, a method of leaving the f'part left unattached and finishing the unattached part f'after removing the exposed part e of the luminaire a and the F cable c is also a method of directly attaching the ceiling. In this case, after removing the exposed part e of the luminaire a and the F cable c, methods such as concrete scrubbing, mortar repairing, sanding, and finishing of the b'part of the upper floor floor slubber b are required. A lot of work is required.

In addition, the F cable c must be wired after the completion of the slab reinforcement and before the concrete is placed. Therefore, the F cable c is a short-time intensive work, which requires a large number of people and the time and date. Due to limitations, desirable work arrangements are not possible.

Since the F-cable c is embedded in the slab, it is a one-time disposable and uneconomical. Since the installation position of the luminaire a in the height direction is fixed, a stepladder is required when replacing the light bulb and repairing a damaged portion, which requires a lot of labor for maintenance.

In addition to the illuminating device, a moving lamp (a cabtyre cable that can be carried in a charged state or the like) and a number of illuminating devices such as the illuminating device a shown in FIG. Lighting devices that use exposed wiring as a power source are often used, such as a mobile floodlight having a relatively large headlight type lighting fixture at the end of a moving electric wire.

However, as the ceiling construction is advanced, the means for suspending from the ceiling is lost, so that the above-mentioned F
The following problems have been pointed out due to the reliance on only the cable-mounted lighting device.

That is, when the light bulb approaches the wall surface and the heat discolors the finishing material, or if it is a combustible material, it may cause a fire. When relying on the F-cable driven lighting system, it is difficult to secure sufficient illuminance. Therefore, in finishing work that requires a certain level of illuminance, workers individually install mobile lighting measures such as hand lamps and floodlights. There is a great risk of power outages, fires, electric shocks, etc. due to the fact that many people carry around with them and bring in a lot of equipment with safety problems.

In addition to this, a wide variety of temporary structures are used in recent construction work, and there is a strong demand for omission of the above-mentioned additional work for the ceiling. Therefore, the applicant of the present invention first disclosed in Japanese Unexamined Patent Application Publication No. Sho 60 (1999) for the purpose of omitting additional work for the ceiling and eliminating various problems when the temporary object is an electrical device.
No. 141963 has been proposed.

[0018]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of a method of suspending a temporary structure and a suspension device according to the present invention.

As shown in FIG. 1, a temporary structure consisting of a Suzuran lamp 2 is suspended on the lower surface side of the upper floor slab 1, and the Suzuran lamp 2 is embedded in the lower surface side of the upper floor slab 1. It is suspended by a suspension body 4 fixed to a fixed member 3 that is present.

The fixing member 3 has a concave cross section, and the suspension 4 has its upper end fixed to the projection 3b in the recess 3a. The fixing member 3 is secured to the upper floor slab 1 by a flange-shaped projection 3c formed around the upper end.

As a means for embedding the upper floor slab 1, as shown in FIG. 3, the slab may be cast by temporarily fixing it to the slab form 5 with nails 6 when the formwork is completed. At this time, if the suspension 4 is wound and stored in the recess 3a of the fixing member 3, the suspension 4 will hang down when the slab form 5 is released from the mold.

The Suzuran lamp 2 comprises a power supply line 2b having a connector plug 2a connected to a distribution board at one end, and a plurality of lighting fixtures 2c arranged at predetermined intervals on the power supply line 2b. The suspension body 4 is suspended from the lower surface side of the suspension body 1. However, in this embodiment, the suspension body 4 and the Suzuran lamp 2 are coupled by an appropriate means.

In the present embodiment, as the device according to the present invention,
A connecting body 8 as a connecting means for connecting the hanging body 4 and the Suzuran lamp 2 to each other.
Is shown. The suspending body 4 is a thin wire having bumps provided at regular intervals, and the connecting body 8 is appropriately selected according to the shape of the suspending body. It requires a first connecting portion 8a to be connected with and a second connecting portion 8b to be connected with the Suzuran lamp 2 which is a temporary structure.

In the present embodiment, as the joint body 8, the joint body 8 having the first joint portion 8a in which one notch is provided in the plate body as shown in FIG. 4 is used. On the lower surface of the first coupling portion 8a,
A second connecting portion 8b is provided which is connected to the Suzuran lamp 2 which is a temporary structure.

According to the connecting portion 8 and the suspension 4, the connection between them is not only the non-slip connection by the frictional force but also the locking connection by the hump, so that there is an advantage that the connecting force is increased.
In FIG. 6, the combined body 8 is fixed to the lower end of the suspending body 4 in advance, and the lower end of the suspending body 4 is lifted and joined in the middle thereof. It is suitable when a suspension means is attached.

At the beginning of the construction work, it is in a suspended state as shown in FIG. 1, and when the construction work is transferred to the construction of the ceiling wall 9, as shown in FIG.
As shown in, the connecting portion of the connecting body 8 to the suspension body 4 is lowered.

This descent is sufficient if the connecting member 8 is slid down with respect to the suspending member 4 because the connecting member 8 and the connecting member 8 are locked by friction. As described above, in the state shown in FIG. 2, if the suspending body 4 is positioned at the joint portion of the ceiling wall 9, it is not necessary to specially process the board material or the like of the ceiling wall 9, and If you do not need the Suzuran lamp 2 after construction, cut the suspension 4
Since the cut surface of the hanging body 4 is minute, it does not become a visible failure.

Further, although not shown, in the case of a straight ceiling having only the upper floor slab 1, when the fixing member 3 is used, it suffices to apply a blindfold outside the cutting of the suspension body 4.
As described above, according to the present embodiment, on the lower surface side of the upper floor slab 1 of the building under construction, the cut portion is assimilated into the pattern or the unevenness of the surrounding ceiling surface, which is visible under normal living conditions. A suspending body 4 composed of a thin wire 4a having bumps 4b provided at regular intervals with a thickness that does not cause a failure is directly fixed and hung down and slidable with respect to the thin wire 4a.
Since the temporary structure 2 is suspended via the coupling body 8 that is prevented from slipping by using the bump 4b of a, the first coupling portion 8a of the coupling body 8 coupled to the suspension body 4 has a thin wire. 4a hump 4
It becomes possible to sufficiently support the weight of the Suzuran lamp 2 which is locked by b and attached to the second coupling portion 8b.

In the above embodiment, the combined body 8 is
Although the plate having the first connecting portion 8a provided with one notch is used, as shown in FIG. 5, the first connecting portion 8a composed of spring scissors and the second connecting portion 8b connected to the first connecting portion 8a are used. May be included.

In the above embodiment, the case where the suspension 4 is directly provided on the lower surface side of the upper floor slab 1 of the building under construction was explained, but as shown in FIG. It may be fixed to the equipment pipe 7 which is a temporary object attached to the lower surface side of 1.

[0031]

As described above, in the method of suspending a temporary structure according to the present invention, in the case of a double ceiling, it is necessary to leave a part of the ceiling surface left untouched until the temporary structure is removed. Since the joints can be used instead of the above, the construction efficiency of the ceiling surface is improved, and the effect on the construction side such as the need for additional repair work including the case of a straight ceiling, and the temporary structure The effect of solving various problems in the case of an electric device such as a lamp is secured, that is, the effect of the applicant's previous proposal is secured, and the suspension is a thin wire having bumps provided at regular intervals, There is an effect that the lifting force of the temporary structure can be improved as compared with a mere thin wire.

Further, the temporary object suspension device according to the present invention comprises:
Since the coupling body is interposed between the suspended body and the suspended object, there is an effect that the suspension height of the temporary suspended object can be adjusted by a simple means such as sliding down, and the effect of the method is obtained. Is extremely effective for
